Cannot change default Java version from 11 to 1.8
I open new terminal and type java -version and see I have Java 11
java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
I want default Java version to be 1.8, so I check that I have Java 1.8 installed which I do because I type /usr/libexec/java_home -V and get
11.0.1, x86_64: "OpenJDK 11.0.1" /Library/Java/JavaVirtualMachines/openjdk-11.0.1.jdk/Contents/Home
1.8.0_192, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_192.jdk/Contents/Home
so I create new profile with vim ~/.profile and set JAVA_HOME and write and save
#!/bin/bash
JAVA_HOME="/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/"
then I close and open terminal and type echo $JAVA_HOME and get correct JAVE_HOME variable
/Library/Java/JavaVirtualMachines/jdk1.8.0_111.jdk/Contents/Home/
but then I type java -version and still get that I have Java 11
java version "11.0.1" 2018-10-16 LTS
Java(TM) SE Runtime Environment 18.9 (build 11.0.1+13-LTS)
Java HotSpot(TM) 64-Bit Server VM 18.9 (build 11.0.1+13-LTS, mixed mode)
so I type directly into terminal
export JAVA_HOME="/usr/libexec/java_home -v 1.8
and I see that java version is now Java 1.8
java version "1.8.0_192"
Java(TM) SE Runtime Environment (build 1.8.0_192-b12)
Java HotSpot(TM) 64-Bit Server VM (build 25.192-b12, mixed mode)
but If i open new terminal , my version of Java is back to Java 11, so I add the export statement directly to ~/.profile
#!/bin/bash
export JAVA_HOME=`/usr/libexec/java_home -v 1.8
but still the default version of Java when opening a new terminal is Java 11.
So I change profile to
#!/bin/bash
JAVA_HOME="/usr/libexec/java_home -v 1.8"
and open new terminal still java -v gives Java 11.
How do do I change the default version of Java on OSX from Java 11 to Java 1.8?
